Description

Technical Field

[0001] This utility model belongs to the field of experimental equipment technology, and in particular relates to a laboratory sedimentation bottle. Background Technology

[0002] Settling is a commonly used laboratory separation technique. Its principle is to use gravity to allow suspended particles in a liquid to gradually settle to the bottom, thus separating the supernatant from the precipitate. This process usually needs to be carried out under static conditions to avoid external interference affecting the precipitation effect. Settling yields a relatively pure supernatant, and the precipitate can be further analyzed or processed.

[0003] In the laboratory, settling is a common procedure, but conventional containers are cumbersome to use when separating the supernatant from the precipitate, with long transfer times and difficulty in precisely controlling transfer accuracy, thus affecting experimental efficiency and accuracy. Therefore, there is an urgent need for a well-designed, easy-to-operate settling bottle that can significantly improve laboratory efficiency, solve the problems existing in the current technology, and meet the needs of laboratory personnel for efficient and precise operation of settling bottles.

[0007] Furthermore, a holding block is fixedly provided at the top of the lifting rod.

[0008] Furthermore, the liquid outlet fitting includes a connecting plate, a pipe body, and an inner limiting ring. The inner limiting ring is fixedly connected to the pipe body. When the bottom of the water level regulating pipe is in contact with the inner limiting ring, the strip-shaped through hole is in a completely unblocked state.

[0009] Beneficial effects: the utility model discloses reasonable in design, with the following beneficial effects:

[0010] 1, the utility model scheme, through setting up vertical inner tube in the bottle body inside, and setting up strip-shaped through hole on the pipe wall, make the liquid above the precipitate can be transferred to the liquid outlet pipe spare and be transported to other containers through pipeline, the separation of supernatant and precipitate is convenient, reduced the operation difficulty, reduced the pipetting time, can greatly improve the laboratory work efficiency;

[0011] 2, the utility model scheme, set up water level adjusting pipe in the vertical inner tube inside, and change the vertical position of water level adjusting pipe through pull rod, and the position of pull rod can be fixed by the top screw limit block and avoid sliding, the position of water level adjusting pipe is accurately controlled for experimental personnel, thereby realizing the accurate adjustment of supernatant pipetting height in the precipitate bottle, ensuring the accuracy of the pipetting process.
